I understand that I can re-use asphalt and concrete paving on the site for this credit, but does this also apply to the 6" type "A" crushed stone aggregate base below these paving types. We salvaged concrete and asphalt paving along with the crushed rock base when we started the project. We then ground this material and placed it back as compacted base material (8" thickness) under a much thinner asphalt paving.

Randy - Yes. Per the LEED Reference Guide (page 359 of first edition): "Projects that crush and reuse existing concrete, masonry, or asphalt on-site should include the weight or volume of these materials in the calculations. Any construction debris processed into a recycled content commodity that has an open-market value (e.g., alternative daily cover material) may be applied to the construction waste calculation." Since your repurposed material is a processed rock base and not natural rock (Land-clearing debris is defined as soil, vegetation, and rocks) and it would have an open-market value, I think you can include it.
